Effective March 6, 2014: The Bureau of Mining Regulation and Reclamation (BMRR) announces updated certified methods for mercury analysis required in Part I.D of the Water Pollution Control Permit.

WETLAB will no longer utilize the analytical method 200.8, Determination of Trace Elements in Waters and Wastes by Inductively Coupled Plasma using Mass Spectrometry, for testing non-potable water from Nevada mine sites.

The updated required EPA analysis is 245.1, Determination of Mercury in Water By Cold Vapor Atomic Absorption Spectrometry. Along with this change, the BMRR is requiring that all tests that occurred in January and February are updated, using the 245.1 analytical method.

WETLAB is currently certified by EPA 245.1 and has already begun to process samples that still remain within the EPA suggested hold time.

WETLAB has also contacted clients to inform them how this change has affected their 1st quarter samples.

Please contact the WETLAB Client Services Manager Kurt Clarkson at 775-355-0202 with any questions.

As Nevada ranchers, farmers and residents brace for a desperately dry summer, one big glimmer of hope is emerging in this third year of drought.

Climate scientists are becoming increasingly confident that El Niño conditions will emerge by the end of this upcoming summer, boosting the chances for a wet, snowy and potentially drought-busting winter next year. El Niño is a climate phenomenon caused by warming water in the Pacific Ocean. In the past, El Niños have produced prodigious winters on the West Coast, including soakers like 1997-98 that dropped more than 36 inches of rain in Sonoma County in February alone. That same winter more than 186 inches of snow fell in February at Alpine Meadows ski resort.

El Niños do not guarantee a big winter, but according to the Western Regional Climate Center, “El Niño usually (not always) brings wetter winters to central and especially southern California. Large El Niños (a very limited sample) appear to extend wet conditions further north.”

Some climate scientist are calling for a 75 percent chance of an El Niño year next winter, which should be welcome news for ranchers and farmers in Nevada who are already planning to stop planting crops this season or reduce the size of their livestock herds because of the scarcity of water.

As skiers, ranchers and farmers know, weather forecasting is notoriously fickle even days before a storm, and predicting winter weather nearly a year in advance is admittedly imprecise. But El Niño’s potential to drench the West Coast with powerful, jet-stream-propelled storms is well documented by climate scientists.

In a winter were storms have been few and far between, that hope of an El Niño winter that will end the drought by filling reservoirs and re-charging aquifers is a welcome piece of positive news. Climate scientists will continue to track the warming Pacific Ocean temperatures through a vast network of buoys. How much the ocean warms over the next several months could have a dramatic impact on whether the winter of 2014-15 is a drought-busting season of storms, or another year of parched conditions.

On January 8, 2014 the water supply for one of the largest water treatment plants in West Virginia was contaminated.  The contaminant was 4-methylcycolhexene methanol, a chemical used to remove impurities from coal. It leaked from a storage container at Freedom Industries, a company that specializes in making chemicals for the coal and steel industries.  The leak was caused by barrier failures that allowed the chemical to flow down a bank and into the Elk River where it traveled one mile downstream to the water treatment plant.

The chemical spill caused a pungent odor to overtake the surrounding area resulting in lead officials from the EPA Air Quality division to discover the leak. Upon investigation, Air Quality division officials notified the EPA Water Quality division, along with management at the treatment plant. A non-use order was immediately put in place for all residents.

The non-use order prohibited water use for all purposes including drinking, cooking, bathing, laundry or cleaning, affecting businesses such as hospitals, motels/hotels, restaurants, schools and grocery stores. And while the water treatment plant serves just 100,000 customers, reports estimated that up to one-fourth of the state’s population was affected by the spill.

TIMELINE

Jan 8^th – Spill Occurred; Non-Use Warning Issued

Jan 9^th – News and Radio Reporting on Issue

Jan 10^th – West Virginia Governor and President Obama declare a state of emergency for 9 Counties

Jan 13^th – Limited Use of Water Allowed After Water System Flush

At the time of the spill the Centers for Disease Control (CDC) did not have a healthy concentration consumption standard for 4-methylcycolhexene methanol; therefore, the chemical was not regulated and had been deemed “non-hazardous.”  The CDC is currently working on the total maximum daily load (TMDL), which is a “calculation of the maximum amount of a pollutant that a waterbody can receive and still meet water quality standards” (EPA).

Some interesting points that are highly relative to WETLAB work:

The chemical has a low odor threshold which helped the detection of the leak

A representative from the West Virginia Water Research Institute said the closest thing he could find to 4-methylhexene methanol for water quality are foaming agents (MBAS).

The CDC decided that a “safe” level for the contaminant is less than 1p.m.

The Sierra’s first snow survey, conducted early this month, indicated what we already knew – it’s the beginning of another dry year.

 According to a recently published article in the Sacramento Bee, California experienced one of the driest starts to winter ever recorded. In fact, in its first snow survey, the California Department of Water Resources found the snowpack at only 20 percent of average – a water supply crucial to both California and Nevada.

In the northern Sierra, according to the Bee, which supplies much of the Reno-Sparks’ area water via the Truckee River, the snowpack is just 10 percent of average.

That stacks up to 9.3 inches of snow depth – 2.3 inches of water content – at Echo Summit near South Lake Tahoe, according to an article in the Sierra Sun.

The results weren’t surprising after 2013’s record-setting drought, the driest in California’s 119 years of data, according to the Western Regional Climate Center in Reno.

“The water situation is bad; we’re kind of in unprecedented conditions. We’re looking at a year that’s potentially going to be worse than the 1976-77 drought,” John Woodling, executive director of the Sacramento Regional Water Authority, noted in the Sacramento Bee article.

Reports by the Reno Gazette-Journal indicate that if the weather keeps up, California will only be able to deliver 5 percent of the water requested by 29 public agencies this year.

“While we hope conditions improve, we are fully mobilized to streamline water transfers and take every action possible to ease the effects of dry weather on farms, homes and businesses as we face a possible third consecutive dry year,” said Mark Cowin, director of the Department of Water Resources in an issued statement.

At Lake Tahoe, officials are already urging conservation, according to the Sierra Sun.

“Every gallon a customer conserves will help preserve the necessary water resources available during a drought situation,” Tony Laliotis, director of utilities for the Tahoe City Public Utility District told the Sun. “Conserving water in the winter is just as important as conserving in the summer.”

The season isn’t over yet though, as some officials have pointed out.

“One giant storm can turn it around,” said Steven Poncelet of the Truckee Donner Public Utility District in the Sierra Sun article.

In the latest chapter on a controversial subject we’ve discussed before on the WETLAB blog, a judge has once again rejected a Southern Nevada Water Authority pipeline aimed at eastern Nevada water.

This is the second time a judge has blocked the project since 2009, according to the Las Vegas Review-Journal, which would siphon billions of gallons a year from eastern Nevada to Las Vegas.

Seventh District Court Judge Robert Estes ruled that Nevada’s chief water regulator needed to recalculate and reduce how much water could safely be taken from Spring, Cave, Dry Lake and Delamar valleys, according to the article.

Estes found that the amount of water proposed would affect other water rights, particularly in Spring Valley, where the project would mean the valley wouldn’t reach equilibrium even after 200 years.

He said the project, “is unfair to following generations of Nevadans and is not in the public interest,” according to the Las Vegas Review Journal.

The proposed project, according to the Las Vegas Sun, would have cost $6.5 billion over 10 years, and has been protested by environmental groups, ranchers and Indian tribes.

If approved, the deal would have taken an estimated 84,000 acre-feet of water. An acre-foot equals 325,851 gallons.

“There is no objective standard to determine when mitigation efforts will be eliminated and implemented,” Estes said in the Sun article, requiring the State Engineer, Jason King, to take steps to avoid potential environmental impacts.

While King said he was disappointed, opponents lauded the decision. And while the decision has been made for now, it didn’t dispute the need for water for Southern Nevada outside of the Colorado River supply – an issue that will continue to arise as time goes on.

The Environmental Protection Agency (EPA) awarded $15 million to the State of Nevada this month, aimed at improving pollution control and drinking water infrastructure, things we think are of the utmost importance here at Wetlab.

The funding goes to the Nevada Division of Environmental Protection (NDEP), broken down into a $6.5 million grant for the Clean Water State Revolving Fund, according to an article found on waterworld.com, and $8.5 million for the Drinking Water State Revolving Fund.

The grants are just the latest in more than $320 million in EPA funding awarded over the last 24 years, according to Jared Blumenfeld, the EPA’s regional administrator.

“Without this investment and creative financing at the federal level, many communities would not be able to provide for Nevadans’ basic needs for clean, safe drinking water and proper wastewater treatment,” Blumenfeld said.

In the past, according to the article, EPA money has funded new well construction aimed at decreasing arsenic levels in Tonopah, as well as advanced wastewater treatment in Clark County to reduce bacteria and chemicals making their way into Lake Mead.

Other water quality projects from the NDEP have ranged from non-point source pollution control, watershed protection and restoration, water efficiency improvements, wastewater reclamation, and other wastewater treatment projects on the Clean Water State SRF side, as well as drinking water infrastructure on the Drinking Water SRF side.

Water Supply News

On the supply side of our state’s water news, southern Nevada looks like it’s going to get some reprieve from dry conditions thanks to a wet fall on the Rocky Mountains’ west slope, according to mynews3.com.

The Colorado River Commission reported rainfall in some areas of up to 50 percent above normal for the month of September, which will help the more-than-half-empty Lake Mead, the primary water supply for Las Vegas.

Lake Mead is at 1,104 feet, anything below 1,075 is considered a shortage.

As the consequences of the government shutdown continue to unfold, one interesting water-related headline popped up in northeastern Nevada – wild horses near Elko that were unable to get water.

The Elko Daily Free Press reported that Jackie Wiscombe, a contractor with the Bureau of Land Management (BLM) who hauled water for wild horses on BLM land, was told to stop.

“Due to the government shutdown, these animals are in dire circumstances with no water available,” she said in an Oct. 10 article.

Following that article, BLM Elko District Director Jill Silvey sent an employee to check on the horses and water conditions, according to a second article published Oct. 12.

Silvey said that hauling water to the horses was considered an essential service, not intended to be shut down, which meant Wiscombe could go back to work.

“I like working with the BLM office,” she said, “and they really do care about these wild horses.”

Winter Weather & Water Update 

Accuweather.com is the latest player to throw its hat in the ring with winter weather predictions, claiming a wet and snowy winter for much of the West.

“With the East as an exception, most ski resorts country-wide should not have a problem getting up and running this winter,” The prediction states. “This season’s precipitation may even bring drought relief to California, replenishing reservoirs and easing water shortages.”

In particular, the forecast calls for heavy precipitation between December and January.

We always take these long-term forecasts with a grain of salt, but its always nice to find an encouraging forecast.

First Lady Michelle Obama has been advocating for people to drink more water in an effort to improve health.

If you’re a fan of WETLAB on Facebook, you’ll know that’s something we whole-heartedly agree with.

According to an Associated Press report, Obama launched the campaign earlier this month in Watertown, Wisc., saying drinking more water is the “single best thing Americans could do to improve their health.”

“Water is so basic, and because it is so plentiful, sometimes we just forget about it amid all the ads we watch on television and all the messages we receive every day about what to eat and drink,” she said in the article.

Mrs. Obama spoke about seeing improvements in her two daughters’ health after deciding to drink more water, but was careful not to attack the soft drink industry, according to the article, because she said healthy changes won’t happen without buy-in from the food industry.

In fact, this campaign is backed by the American Beverage Association, which represents makers of soda, sports drinks and energy drinks, according to the article, but many of those companies also make bottled water.

This is where some environmental groups take issue.

“We applaud the first lady’s initiative to encourage people to choose water over sugary beverages, but we do have concerns that this partnership is working in conjunction with the bottled water industry and with that instead she were encouraging people to choose the much more affordable, more regulated option of tap water,” said Emily Wurth, water program director for Food and Water Watch in the article.

The issues are two-fold: the waste created by disposable water bottles (about ¼ of plastic water bottles are recycled according to Wurth) and tap water is held to higher quality standards than bottled water, which often comes from municipal water systems anyway, making the premium price questionable, according to the article.

Local Water News

In northern Nevada Water news, winter forecasts are starting to turn up, offering interesting predictions into Sierra snow pack and our subsequent water supply. The Farmers’ Almanac is calling for a cool winter with near-normal precipitation, which would be an improvement over the last two years. But the National Climate Prediction Center is having a tough-time nailing down a prediction, reporting “equal chance of being below normal or above normal for snowfall for the western states.” Only time will tell, but we’re keeping our fingers crossed.

As summer comes to a close, another dry season has taken its toll on Southern Nevada water supplies.

Drought conditions have dropped water levels in Lake Mead to “near critical levels,” according to 8newsnow.com, putting Las Vegas Valley water supply in a tight spot.

The situation has gotten bad enough that Las Vegas water officials may seek federal disaster aid, according to ktvn.com.

In a comment to the Las Vegas Review Journal, Southern Nevada Water Authority chief Pat Mulroy compared the severity of the situation to Hurricane Sandy, which hit the East Coast last year.

Lake Mead’s water level has dropped more than 100 feet since 2000, according to ktvn.com.

If Lake Mead drops to 1,075 feet, Nevada will be forced to cut water usage by 4 percent, according to 8newsnow.com. The lake was at 1,106 feet, as of August 8, and falling fast.

The Southern Nevada Water Authority cannot pull water out of Lake Mead if it drops below 1,000 feet, but is drilling a third “straw” into the lake to gain deeper access in case levels continue to drop.

Many are viewing this as a long-term issue, and one that will have to be dealt with on a larger scale.

“They really all see, as do most scientists, the fact that we’re not really in a period of drought. It is climate change,” Dr. Stephen Parker of University of Nevada, Las Vegas, told 8newsnow.com.

And according to federal water experts and climatologists, the picture is grim for all of the South West that depends on the Colorado River for water, according to an article in the Las Vegas Sun.

Demand for water from the Colorado River exceeds current supply, according to the article, meaning the government may have to spend between $4 and $7 billion to ensure a more stable supply for Nevada, Arizona, California, Utah, Colorado, Wyoming and New Mexico.

This situation only reinforces the importance of properly, and carefully, managing not only our water supply in the west, but insuring the water we do have is kept at high water quality standards so it isn’t wasted.

As we’ve discussed before, Lake Tahoe gets a lot of attention from both Nevada and California regarding water quality.

Tahoe’s clarity – measured by the depth at which a white disk can be seen from the surface – is the standard used to gauge the alpine lake’s health. But the measurement is taken near the middle, not the shore, painting an incomplete picture of Tahoe’s true health.

But that’s about to change, according to an article from the Nevada Appeal, when the Desert Research Institute (DRI) launches a boat that will collect new water quality data. Thanks to new funding, DRI will conduct regular testing in shallow water environments around Lake Tahoe for the next three years.

“This will give us an idea of what areas of the lake are threatened, what are the hot spots,” DRI staff scientist Brian Fitzgerald told the Nevada Appeal.

The group is using a jet-powered craft, which can go into shallower water than a prop-driven boat, according to the article, and can take continuous readings as it moves along the lakeshore.

The DRI boat will take water quality measurements including turbidity, translucidity and chlorophyll content, all components of clarity.

As explained in the article, this new data should give scientists a much better handle on what impacts Tahoe’s clarity, as the majority of clarity-reducing pollutants enter the lake as runoff in these shallower zones.

“The near-shore is where it happens,” Fitzgerald said to the Nevada Appeal. “It’s where the interactions are, where the sediment is coming in.”

The study should identify the most impacted areas, allowing cleanup efforts to be focused in the right places to improve water quality and clarity.

We’re interested in following the results of this study, to see what the near-shore water quality monitoring does beyond the already-successful measures taken in the past to bring back Lake Tahoe’s legendary clear waters.
